Which are the slowest frequently applying nodes in Unreal Engine?

@AlienRenders

What do you have that uses subsurface scattering?

Do I need to look at each material to see this?

@AlienRenders

And do you have a lot with transparency?

For example, windows.

@AlienRenders

Do you have water or something in your level?

Yes, I have water.

@AlienRenders

Can you turn off foliage? Just set it to not visible in game. Does that make a difference?

No, it doesn’t.

@AlienRenders

Also, just to rule it out… can you check your project settings->Engine->Garbage Collection and make sure the “Time Between Purging Pending Kill Objects” is not low. Around 60 seconds is the default I think.

@AlienRenders

Not sure if it’s related to foliage or something to do with the landscape materials.

Material shader is complex but all the textures are just 1K.

@AlienRenders

Or the size of the landscape.

24 km² are in the memory from the point where I test.
